Working Theory

If you're looking for even more performance, replace the factory diffusion middle muffler on your Lincoln Navigator with a high-flow absorption exhaust. Performance diffusion muffler is most commonly used by hi-flo pipe manufacturers as it provides the least resistance to the exhaust gases that pass through while a diffusion exhaust used by car manufacturers splits the flow of the exhaust gases up into a series of different paths using a series of plates tubes called baffles. high flow performance is the product of custom engineering these Magnum free-FLO middle exhausts to deliver engine exhaust systems. The result is optimally low gas restriction across the exhaust pipe combined with notable added HP and incredible pep. With our 17 years of producing innovative developments of exhaust systems that truly bring significant performance-gains and revolutionary exhaust system tones, Magnum has become the benchmark for high flow pipe parts in Europe. We are committed to complying with car enthusiasts' requirements in regarding to engine pony, sound level, appearance, reliability and quality.

diffusion perf-tube design is most commonly used by high flo exhaust manufacturers as it provides the least resistance to the exhaust gases that pass through. Lincoln Navigator absorption exhaust for flowing exhaust gases from internal combustion engines comprises an oblong-shaped body a parallel inlet and an outlet pipes are connected into the front wall and extend substantially up to the rear wall, and a straight through perf tube connected in between the inlet and outlet pipes.

Your Lincoln Navigator absorption middle muffler works by having a straight perf tube that's en-cased or wrapped in acoustical fill material. acoustical fill also referred to as silencer fill is provided along the length of the inlet the outlet channels and the connecting channel, and fills the wall space between adjacent convolutions of the inlet and outlet channels the space between either one of the convolutions the chamber-wall, and between the connecting channel and the body-wall. In this design, the exhaust gases are able to pass through with low resistance while the various frequencies of sounds produced by the gases are absorbed by the acoustic fill around the perf tube.

Racing-inspired performance

Magnum exhausts deliver power capability evenly to your Lincoln Navigator across the RPM range. Exhaust Mufflers in general A factory exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine's combustion chamber to the free air and includes several exhaust elements.

Exhaust Muffler

A device used to attenuate sound while also allowing fluid (usually gas) to flow through it; also known as silencer in British usage. Mufflers are extensively used to reduce the intake and exhaust noise from pumps, fans, compressors, and internal combustion engines. Although active noise control techniques are emerging, most mufflers continue to use passive silencing methods. Passive mufflers are categorized as reactive or dissipative based on their primary method of attenuation. Reactive mufflers reflect sound back toward the noise source, and dissipative mufflers use porous materials to absorb the sound.

Collector header

In most production engines, the manifold is an assembly designed to collect the exhaust gas from two or more cylinders into one pipe. Manifolds are often made of cast iron in stock production cars, and may have material-saving design features such as to use the least metal, to occupy the least space necessary, or have the lowest production cost. These design restrictions often result in a design that is cost effective but that does not do the most efficient job of venting the gases from the engine. Inefficiencies generally occur due to the nature of the combustion engine and its cylinders. Since cylinders fire at different times, exhaust leaves them at different times, and pressure waves from gas emerging from one cylinder might not be completely vacated through the exhaust system when another comes. This creates a back pressure and restriction in the engine's exhaust system that can restrict the engine's true performance possibilities.

Pipe (tubing)

An exhaust pipe is usually tubing used to guide waste exhaust gases away from a controlled combustion inside an engine or stove.

Emission Control

An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sonda or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to the engine management ECU computer, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.

Catalytic converter

In automobiles, a component of emission control systems used to reduce the discharge of noxious gases from the internal-combustion engine. The catalytic converter consists of an insulated chamber containing pellets of catalyst through which the exhaust gases are passed. The exhaust's hydrocarbons and carbon monoxide are converted to water vapor and carbon dioxide.

Please read instructions before installation.

REQUIRED SKILL LEVEL:Skill Required – Exhaust fitter recommended

REQUIRED TOOLS: Tools Required – MIG-, TIG-, or Flux welder

ESTIMATED TIME OF INSTALLATION: 30 up to 60 Minutes

This middle exhaust muffler is not Bolt-on to your Lincoln Navigator. It installs with Weld-on universal installation that might require exhaust modification. Should you come across any question feel free to contact our Product Specialists 7 days a week.

Though exhaust shops working at different rates, the following chart may be used as a reference. The estimated costs are determined as per our 17-year service experience and based upon our partners' labor charges. Please check with your installer prior to purchase.

Place the muffler next to the factory muffler. You have to check where to cut the piping and where to weld on the new exhaust inlet pipe. You may mark that cutting point on the Magnum exhaust inlet pipe with a permanent marker.

Decide how and where you want to hang the muffler to, use the factory bushing and their points or create new ones.

Cut out your old muffler off using handsaw, power saw, reciprocating saw or angle grinder. The factory muffler is suspended by exhaust bushing or mount, that will need to be removed as well.

Start the engine and check for leaks. You will feel air escaping from the muffler attachment location if it isn't on correctly. If no air is escaping, you've completed the job.

Do not create stricture toward the exhaust ends, Magnum Performance Exhaust's internal diameter where two pipes are connected should be larger or equal to the factory pipe's diameter. Any stricture can cause power loss.

Though the universal installation can be completed easy, we strongly recommend having a certified tech install this performance exhaust. An average exhaust shop can do it for you.

Protect the tips against scratching, hot metal chips, etc. in order to keep its mirror finished outlook.

When you first crank the engine, the exhaust sound you hear is provisional. The sound will change after the first 100...150 miles (160...250 Km) or 5-10 hours operation, because the acoustical fill has to be arranged uniformly within the exhaust chamber. After the muffler is finished and ready to install, the fill amorphous inside. High temperature and gas low makes it homolog. This process takes time, please be patient.

Exhaust will not perform as expected in case of serious oil consumption of the engine. Burnt oil can clog the filling accordingly the gas restriction will significantly change. This malfunction is not covered by factory warranty as well as it will affect the sound and performance of your exhaust.

Regardless of manufacturer, high flow exhausts are not capable to deliver such low noise emission as factory exhaust produces. Expect louder but quality sound.

Warranty voids if vehicle is used for racing.

This exhaust is an off-road part. Magnum mufflers are not CARB Approved, and are never to be used on Pollution Controlled Vehicles or on Public Highways in those states and countries where emission control law is in effect.

Added some power

This muffler is simply great. I highly recommend it. Exhaust note didnt become obnoxiously loud, but still a humming sound. On a side note you have to weld it so dont expect install it bolt-on. Added some power to my truck. Delighted with the professionalsim of tech support.

more horsepower and great sound

I have the magnum expansion perforated tube exhaust. They are so easy to weld on and mount to the vehicle. It definitely gave me more horsepower and great sound. Well worth the upgrade to your old truck. I will recommend to anyone.

Magnum decat replaces the factory restrictive catalytic converter. Decat pipes allow the exhaust gasses to flow much more freely, boosting the power output and improving throttle response. The common reason enthusiasts decat their vehicles is because a stock catalytic converter can be a large restriction in the exhaust system, and removing it can free up noticeable amounts of horsepower and can notably boost fuel mileage. Scrap restrictive catalytic converter that robs you of horsepower.
